Abstract |
In this work we provide predictions for bottom-strange molecular states within the Hidden Gauge Formalism. We study the coupled-channel scattering of B(& lowast;) K(& lowast;) states and, by fixing only one free parameter to obtain the mass of a new excited Bs0 state seen by the LHCb, we predict the pole parameters of six states in this sector. Concretely, we get that the masses of the flavor partners of the Ds0(2317) and Ds1(2460) states in the bottom sector are 5760 and 5802 MeV for the BK (JP = 0+) and B & lowast; K (1+) states, respectively. Moreover, the recently seen states by the LHCb with masses around 6100 and 6160 MeV can be interpreted as BK & lowast; and B & lowast; K & lowast; molecular states, according to reasonable values of the pole parameters and the splitting between these two states obtained in our calculation. |
